On Margaret Mead's "Balinese Character" sent by Hamburger as a christmas gift. On reading Stefan Zweig's "The World of Yesterday".
On Margaret Mead's "Balinese Character" sent by Hamburger as a christmas gift. However, Holtfreter is disgusted by Bateson's & Mead's scientific approach.
On the importance of embryology for cancer research: "Der Unterschied wuerde hinfaellig werden, wenn es uns edlen Embryologen gelaenge, all die aufghehaeuften Weisheiten der Genetic (sic!), Embrologie, Microbiologie, Immunologie, Biochemie und Pathologie zu verdauen und dem Leserpublikum so mundgerecht zu machen, dass nur wir Embryologen den Schluessel zum Krebsproblem in der Westentasche haben." On his X-ray experiments.
References for their chapter in 'Analysis in Development'.
On the future of Analytical Embryology. On references for Holtfreter's chapter.

Review of F. O. Schmitt's chapter in "Analysis of Development". "He has not a single word for all my efforts trying to relate the lipo-protein structure of the cell membrane (of which he speaks a lot) to the biological phenomena of cellular adhesion, locomotion, cell division, differentiation. Instead he glorifies the blah-blah of Weiss."

On the outline of one of their book chapters.
On the correction of the manuscript.
